AAAC, or All Aluminium Alloy Conductor, is used as a bare overhead conductor for power transmission and distribution lines. Its advantages over its counterparts, AAC and ACSR, are that it has a higher mechanical resistance than AAC, and better corrosion resistance than ACSR. Additionally, AAAC has better strength to weight ratios and therefore better sag characteristics than the other two.
AAAC is a homogenous concentric-lay-stranded conductor made from round aluminium alloy wires. AAAC conductors are available in single and multi-layer constructions.
These choices provide the necessary strength and the current carrying capacity forgiven applications.
AAAC conductors are manufactured in accordance with the following Standards:
The high strength to weight ratio provided by the aluminium alloy makes the homogeneous construction of AAAC conductors a preferred choice for transmission and distribution projects where:
